Building a replica 1910ish engine and bike. Using a B-29 Super Fortress APU cylinder, a Yamaha YZ250 Crank and rod. Piston is a 225 Yamaha. The crankcase I am casting from Aluminum. Cams are Briggs FH. I am a Youtube creator, so I am building it step by step on there.

Have you thought about using casting wax instead of the wood to make your molds? I have used this method to make my own casting wax, fairly reasonable to make and easier than wood to make molds. http://www.instructables.com/id/Machinable-Wax/
